Question

希望你们能帮助我。我对phonegap相对比较新。我已经开始了一个星期+现在关于这个问题。我在C＃中有一个dbase wcf rest服务，并且已经构建了一个Android客户端来调用这个服务。当我在wp7中测试这个应用程序时，似乎一切正常工作，即以json格式调用此服务。但是当我将这个应用程序迁移到eclipse android环境并配置相关设置时，即使我将url：http //：localhost：1067 / Service1更改为http //：10.0.2.2:1067/Service1后，应用程序也无法成功运行。我还在使用我已修改为以下

正如我之前所说，我已经使用vs2010服务器和iis7在本地测试了wcf服务它似乎运行良好，但我无法让它在Android中工作。任何帮助将不胜感激。提前谢谢。

Answer 1

我发现这个代码没有错，除了取消评论评论的白名单部分，即转换：

<!-- <access origin="https://10.0.2.2*" subdomains="true" /> such as above, but including subdomains, such as www --> to

<access origin="https://10.0.2.2*" subdomains="true" />

并解决了它。
